java - Use String.split() with multiple delimiters

Question

I need to split a string base on delimiter - and .. Below are my desired output.

AA.BB-CC-DD.zip ->

AA
BB
CC
DD
zip 

but my following code does not work.

private void getId(String pdfName){
    String[]tokens = pdfName.split("-\.");
}

Answer 1

I think you need to include the regex OR operator:

String[]tokens = pdfName.split("-|\.");

What you have will match:
[DASH followed by DOT together] -.
not
[DASH or DOT any of them] - or .
